This paper summarizes experience gained over the past ten years in applying multivariable control techniques to a pilot scale, double effect evaporator at the University of Alberta. Since this same apparatus has been used in each investigation, it is possible to make meaningful comparisons between conventional control strategies and modern multivariable techniques including: Optimal control, eigenvalue assignment, state estimation, adaptive control, frequency domain methods, time delay compensation, disturbance localization and model reference identification. The paper concludes with a discussion of the implications of this research for industrial application.
